TEWKSBURY TWP. — Some of the jokes were as corny as the fields around Hickory Grove Farm. But that’s what the audience expected and the performer “Johnny Counterfit” and his band The Time Travelers obliged on Saturday afternoon.

They were the featured performers of the Hickory Grove Opry, at Hickory Grove Farm on Farmersville Road near Califon.

What started as a Thursday night jam session in the barnyard of the family farm eventually became The Hickory Grove Opry. The storage barn is used three or for days each summer for a tribute organized by Ellie and John Burd to honor The Burd Boys, one of New Jersey’s most popular country music bands in the ’60s and ‘70s.

Counterfit presents a show featuring voice and singing impressions of some of the most famous singers, actors and politicians of the time. He claims to do more than 165 impersonations.

Among the many singers he imitated were Johnny Cash, Marty Robbins, Dean Martin and Eddy Arnold. He threw in the voices of John Wayne and Jimmy Stewart, too.

And there were former president: his Richard Nixon sang “I keep a close watch on these tapes of mine,” sounding like the Cash hit I Walk The Line and reminding the audience of the Watergate scandal of more than 40 years ago and how the existence of the secretly-made audio tapes of White House meetings came out during public hearings on the matter.

Then there was Bill Clinton singing Go Away Little Girl, in reference to his affair with White House intern Monica Lewinski.

On and on the show went, one historical figure after another. Making a special appearance was Ann Brown and Constantly Country. DJ “Doctor D” (Dan Torrone) of Clinton served as master of ceremonies.
